- 'Custom chip off the old block'
-
- - It's a busy time for Acorn, Ian Burley assesses the company's four new
- computers.
-
-
- Today, Acorn will announce four new computers, including the worlds first sub-
- #500 RISC system. Three of the new machines use a development of the ARM
- (Acorn RISC Machine) processor, the fourth is the result of Acorn joining
- forces with Psion to badge-engineer a custom version of the Series-3 pocket
- organiser.
-
- Acorn Prefers not to use the original Archimedes logo any more: the three new
- machines running Acorn's proprietry RISCOS (Reduced instruction set computer
- operating ststem) are dubbed the A3010, A3020, and the A4000.
-
- Both the new A3010 and A3020 resemble the three-year-old A3000, though the
- case is slightly taller and has a more steeply-angled keyboard. The #499
- one- megabyte A3010 is aimed at the consumer market: it has a pair of
- joystick ports, a TV modulator, a grey case and bright green function keys.
-
- The A3020 retains Acorn's traditional cream finish and red function keys to
- denote that it's a schools computer. It has two megabytes of memory, expandable
- to four (as is the A3010), the joystick ports give way to a networking
- interface option, and IDE hard disc controller circuitry is built in. An A3020
- with a 60 Mb hard drive and standard resolution colour monitor will sell for
- #899, or for #749 without the hard disc.
-
- The A4000 - #949, including an 80 Mb hard disc - has the same electronics as the
- A3020, but housed in a more conventional metal box with a seperate keyboard. The
- keyboards on all the examples I tried were disappointing and lifeless. Both the
- A3020 and A4000 are compatible with Acorn's new AUN (Acorn Universal Network)
- hybrid networking environment. This provides a common RISCOS-based user
- interface on both the traditional Acorn Econet system used by many schools
- and standard Ethernet networking.
-
- The new machines' most impressive technical feature is a large custon chip that
- integrates the four seperate circuits - ARM processor, IOC input/output
- controller, VIDC video and sound chip and MEMC memory controller - which made
- up the original ARM chip-set.
-
- This new ARM 250 chip does not use the newer ARM-6 series technology destined
- for Apple's Newton electronic organiser. However, the ARM 2 processor core is
- clocked at 12 MHz, 50 % faster than the originals 8 MHZ. Acorn rates the ARM
- 250 at 6 MIPS (million innstructions per second) and claims it is 40 % faster
- than a 386 DX PC chip. Performance can be more than 50 % better than the 8 MHz
- ARM 2 Archimedes because programs won't need to slow down so much when a lot
- of bus bandwidth is claimed by the video circuitry.
-
- One application which works surprisingly well on the new machines is the new
- version of PC-Soft, Acorn's PC emulator. The long standing problem of lethargic
- CGA-resolution graphics has been solved: the latest release now behaves like
- a perfectly respectable PC/XT with a colour VGA screen.
-
- Like the A5000, introduced last year, and the A4 notebook launched last month,
- all the new models use a Chips & Technologies PC input/output controller for
- serial and parallel ports plus the floppy drive. This offers 1.6Mb Acorn and
- 1.4Mb PC compatible formats. They have one "mini-podule" expansion slot,
- compatible with the older A3000, but no external full-size podule card
- expansion slot as on the A3000. For the A3020, this disadvantage is minimised
- because the internal hard drive doesn't use an expansion slot. An A3010 owner
- must use that slot to add a hard drive, and so won't be able to add a scanner
- interface or whatever. But Acorn say it isn't aiming the A3010 at people with
- those requirements: they should go for an A5000.
-
- RISCOS 3.1 is now officially released. ROM chip-sets are available to A5000
- owners for #19 (without manuals) and to all other RISCOS users for #49
- (including manuals). Owners of older Archimedes 310 and 400 machines may
- need a hardware upgrade costing #30. RISCOS 3.1 enhancements include a dozen
- outline fonts in ROM, faster graphics, printer drivers that work in the
- background, and a nice new bas-relief look to the desktop.
-
- Acorn's biggest surprise today must be the unveiling of its new Pocket book
- organiser, based on the 256K version of the Psion Series-3. Being aimed at
- students it has a spreadsheet as standard, at the cost of the Series-3 diary
- software, though this is available as an optional ROM cartdidge. The Pocket
- book's recommended price is identical to the Psion version at #249.95
- including VAT.
-
- Naturally you can hook your pocket computer up to a RISCOS computer. On the
- screen the Pocket books files appear in a standard directory viewer and can
- be "dragged and dropped" in the usual way.
-
- How will they do ? The A3020 is a much improved A3000 for roughly the same
- money: Acorn is confident it will maintain the A3000's achievement of being
- the best selling computer in schools. The future of the A3010 is harder toi
- predict. Several high street multiples are declaring undying devotion to
- Acorn's new baby, but since Commodore has just cut the pribe of the Amiga 600
- to #299, the battle may already be lost.
